Sprite Request - Sephiroth + Safer Sephiroth (Monster Sprites)

I went on TSR and found nothing... No sprites anywhere on that japanese database site. And Google didn't helped either. Man, I wish there was some Sephiroth sprites, like, in the overworld and monsters to replace Kefka, but I found nothing, so I can't replace Kefka at all... Also, does someone know any tool to edit a character's name in the game?
